colosseum 3d model

Create a high-fidelity 3D model of the Roman Colosseum, accurately depicting its elliptical architecture, tiered seating, and multi-level arched facade. Include the central arena with concentric rows of stone benches and the upper velarium system with retractable awning supports. Use realistic textures for travertine, tuff, and brickwork, showing weathering, erosion, and historical wear. Model structural details such as radial corridors, vomitoria (exit passages), and column orders (Doric, Ionic, Corinthian) across levels. Ensure proper scale and proportions based on historical references. Optimize for real-time rendering with LODs and clean topology. Final output should support PBR materials, ambient occlusion, and baked lighting for cinematic presentation.
